Excavation by Archaeological Survey of India in Gottiprolu, Andhra Pradesh indicate it as a Trade Centre of Early Historic Period
2000 year old brick structure and a Vishnu sculpture also unearthed
The 1st phase of excavation by a team of Archaeological Survey of India’s Excavation Branch – VI, Bangalore at Gottiprolu near Naidupeta in Nellore  district, Andhra Pradesh has discovered the remains of a huge settlement surrounded by a massive brick enclosure. Among many other antiquities unearthed are one life size Vishnu sculpture and a wide variety of pottery of the early centuries of current era.
The site of Gottiprolu  lies on the right bank of a distributary of river Swarnamukhi about seventeen kilometers east of Naidupet and eighty kilometers from Tirupati and Nellore. Detailed topographical study and drone images have helped in identifying an early historic settlement surrounded by a fortification and the possibility of a moat encircling it. The fortification is very much clear on the eastern and southern sides of the mound while its other arm seems to have been leveled as a result of modern settlements.

The most outstanding discovery is of massive sized brick enclosure wall at the southern part of the mound. This structure is of baked bricks and exposed to a length of more than 75 meters with an average width of about 3.40 meters, which rise to a height of nearly 2 meters and runs in a curvilinear pattern towards the northern end of the mound.

The available brick sizes  are comparable with the Satavahana / Ikshvaku period structures in Krishna valley i.e. Amaravati and Nagarjunakonda. On the basis of the brick size and associated findings they can be placed anywhere between 2nd – 1st century BCE or little later .
Apart from the excavated remains, one of the most major find was the discovery of a buried Vishnu sculpture from the western part of the village.

Subsequent excavations conducted around the image revealed it to be a life size image of Vishnu measuring about 2 meters in height. It displays a four-armed Vishnu standing over a pedestal carrying chakra and conch in his upper right and left hands respectively. The lower right is in bestowing boon and the left hand in katihastha  posture. The iconographical feature like the elaborate head gear, thick holy thread and decorative drapery dates it to Pallava period .

The findings of assorted stone tools of Palaeolithic and Neolithic
periods from secondary contexts suggest that prehistoric people also occupied this area. Further studies are being carried out through geological, chemical analysis of the site/samples.

These settlements could have been an important trade centre as indicated by the presence of imitated amphorae wares that were mostly used to transport liquid commodities.

The proximity of the site to the seacoast suggests that the site could have served as a strategic settlement involved in maritime trade. Further research will reveal interesting facts about the site as trade centre.
Other major retrieved antiquities unearthed are copper and lead coins, iron spear head, stone celts, terracotta beads, ear stud in semi precious stone and hopscotches. The ceramic assemblage of the site consisted of fine quality black and red ware collected from the lower levels, conical jars, rouletted sherds, russet coated ware etc. The extensively used goblet shaped ware indicates the typical table ware associated with the site.

Explorations conducted in and around Gottiprolu within a radius of 15 kilometers revealed important vestiges viz., fortified early historic settlement at Puduru, Sunbrahmanya temple at Mallam, unique rock cut laterite stepped well at Yakasiri, Vishnu temple at Tirumuru. Further the entire seacoast on the east is dotted with various forms of antiquarian remains extending from Tamil Nadu and culturally linked with each other.
The two fortified townships within the gap of 15kms during early historic times indicates the significant strategic location was preferred by the early historic people for trade in the region keeping in view of proximity of the sea, River and Lake .
